The library is a major scholarly resource for members of the University of Cambridge and external researchers. It is often referred to within the university as the UL. Thirty-three faculty and departmental libraries are associated with the University Library for the purpose of central governance and administration, forming "Cambridge University Libraries".

Cambridge University Library is one of six legal deposit libraries under UK law. It holds about 9 million items and, through legal deposit, purchase and donation it receives around 100,000 items every year. The University Library is unique among the legal deposit libraries in keeping a large proportion of its material on open access and in allowing some categories of reader to borrow from its collections.
